+
+## Returns
+
+## Open horizons
+- 2026-06-26T (wake) — PULLING THREAD: Chamber Library spec §§II-III ratification → build OCR+EPUB normalizers → conformant graduation (HELD). Graduation uncommitted in chamber-library working tree by intent; do not commit until spec ratified.
+- Sub-question to resolve early: did Books 1-3 finish OCR-ing on CapableHands (PID 2653) overnight, and are they clean? (one ssh check)
+- Carried drift to hold: careless-edit-boundary — verify what a "stray" line MEANS before deleting, esp. in another's file with no git history (la-chute `\`-spacer strip, recovered 06-25).
+- Governance debt: REVIEWED-44 (operations.yaml) owed on paper by steward; CapableHands password rotation (steward-supplied in-session).
+- 2026-06-26 — Sidecar typology + orchestration thinking CAPTURED durably (the steward's "don't lose this trail"): `studium-engine/docs/the-sidecar-typology-and-orchestration-2026-06-26.md`. Anchored against charter §VI/§VIII/§X/§XIV. Holds: the admission test (hash-relationship + staleness-trigger → derived/authored/relational); silence_zones = the §VI accountability organ at debate scale; 3 constraint-candidates (O(n²) relational → engine-derived+cached; persona-never-licenses-warrant; hash-check-at-summon-time); §XIV inquiry-record = the L1 seam (the held studium↔L1 question's foundation). Engine-governance, NOT corpus-spec — does not reopen §VI ratification. Untracked in studium-engine repo.
+
+## Awaiting
+- 2026-06-26 — Reading-index finding relayed to jurist (steward passing). Material to §VI: THREE layers verified, not two — (1) canonical text + provenance + bare `voice:` tag; (2) reading-index sidecars (`reading-indices/*.yaml`, 4 exist, derived + hash-bound + interpretive: core_claims/key_images/silence_zones/kingdom); (3) voice personification frontmatter IN 84 canonical texts (voice_role 84 / semantic_profile 36 / voice_tradition 21 / voice_period 21). Navigation ≠ persona. Jurist to shape: one-manifest-vs-two, keep `voice:` tag, confirm gate-verifies-only-against-canonical invariant. §VI redlines HELD until jurist answers (the answer shapes wording). Steward authorized §§II–III/§V/§VII/§X to fold; redlines prepared in holding form on jurist return, then REVIEWED-45 + PENDING (§VI split).
+
+- 2026-06-26 — Steward ratified §V + §VI ("yes and yes"). FULL package APPLIED to `chamber-library/docs/chamber-library-specification.md` (6 edits: header status, §III sectionless sentence, §V three-tier verbatim guarantee, §VI two-sidecar architecture, §X antechamber + the byte-faithful→verbatim spec↔spec coherence fix, §XI status). PENDING-42 written (dotfiles real target — PENDING.md is a governance symlink). **REVIEWED-45 owed from steward** (did NOT write — constitutional constraint #1: Claude Code cannot write REVIEWED.md). Graduation now UNBLOCKED (pending normalizer build), no longer held. No git commit.
+
+- 2026-06-26 — OCR check (SSH key access established to CapableHands): **Books 1-3 finished overnight + verified clean.** Ran sequentially (book1 13:52→book2 20:38→book3 03:06 Jun26); PID 2653 gone; pages 491/658/714; each ends on its legitimate series back-matter page (not truncated). **Pathology census (whole-file grep, complete coverage): 0 JSON-leak, 0 raw-brace, 0 null-marker.** Detector validated (fired 23 on the pre-splice dirty book4 scratch). Two count-smells eyeballed → benign (identical "BOOK FOUR" endings = publisher 4-book series listing; 35-41 dot-loops = legit ToC leaders). SCOPE: pathology census complete; deep prose-quality endpoint+ToC-verified only — run `verify_conversion.py` before graduation. NOTE: scratch `alexander-book4-luminous-ground.md` is the STALE pre-splice dirty copy (fixed book4 lives in chamber-library tree) — don't confuse. Books 1-3 are raw conversions (still `## Page N`-marked) → ready to FEED the OCR normalizer (the thread).
+
+## Confidence to recalibrate
+
+## Authorization moves
+- 2026-06-26 — Jurist disposition on Chamber Library spec received. §§I,II,IV,VIII,XI ratifiable as-is; §III ratifiable +1 sentence (sectionless citation); §V needs draft (jurist proposed 3-tier); §VI structural recommendation (corpus=archival / engine-manifest=interpretation — ARCHITECTURAL, [ESCALATE]-adjacent, connects to held studium-interaction Q); §VII gate fix unblocked; §X antechamber clause gap. Graduation HELD (jurist + spec concur). Executor concurs broadly; two refinements surfaced (byte-faithful↔verbatim internal contradiction; prefer-not-to-normalize-characters tightening). Awaiting steward authorization — no spec edits/commits made.
+
+## Milestone
+- 2026-06-26 — **FIRST SPEC-CONFORMANT CHAMBER GRADUATION: Levi *The Drowned and the Saved*.** Built the reusable OCR→canonical pipeline (`normalize_ocr.py` mechanical layer w/ dict-validated de-hyphenation + doubling auto-resolution + verbatim word-guard + conversion record; `insert_chapter_headings.py` per-book curatorial structure map). Graduated: raw→`converted_texts/` (§III provenance), clean canonical→`canonical_texts/` (§IV/§VI frontmatter, epigraph kept, 10 chapter headings, apparatus trimmed), verify_conversion PASS, catalogue 1286. Steward: "crossed a milestone, set an excellent precedent." 
+- **Follow-ons owed:** (1) studium-engine manifest re-point `levi-gray-zone` Complete-Works-omnibus(Goldstein)→this standalone(Rosenthal 1988, the designated Making source) — engine-governance migration, flagged not done; (2) remote olmOCR driver page-number-preservation note BLOCKED by auto-mode classifier (governed home = runbook known_gaps.next, DONE; remote comment = steward to add or authorize); (3) Alexander Books 1-4 next via the proven pipeline (ToC structure more complex — 4-vol reprinted ToC/Roman numerals/per-book page restarts).
